Questione giuridica chiave
Whether the appeal was admissible despite non-payment of the required advance on costs.
Decisione estratta
No. The appeal was inadmissible because the advance on costs was not paid within the time granted, including the additional period.
Motivazione estratta
Under Art. 62(3) LTF, failure to pay the requested advance within the set deadline leads to inadmissibility; the court therefore did not examine the merits.
